Impact of Isolated Tricuspid Valve Repair on Right Ventricular Remodelling in an Adult Congenital Heart Disease Population

Background: Surgical repair of isolated congenital tricuspid valve (TV) disease is rare with no well-defined indication and outcomes. Moreover, the role of right ventricle (RV) in this context has not yet been investigated. Objectives: We sought to assess the impact of congenital TV repair on cardiac remodelling and clinical-functional status and the importance of the RV function in an adult congenital heart disease (ACHD) population. Methods and Results: From January 2005 to December 2015, 304 patients underwent TV surgery in our centre. Of these, 27 (ACHD) patients had isolated TV repair. Patients were evaluated with preoperative and post-operative trans-thoracic echocardiogram. Survival rate has been investigated with a mean clinical follow-up of 3.7 ± 2.3 years while the mean echocardiographic follow-up was 2.9 ± 1.8 years. The clinical and functional status of patients showed a statistically significant improvement after the surgical repair in terms of NYHA class (66.7% vs 7.4%; p
